Which statement is NOT a component of a Maisonneuve fracture?

• A. Fracture of proximal fibula
• B. Medial deltoid ligament sprain
• C. Disruption of tibiofibular syndesmoses
• D. Distal tibial plafond fracture

Answer: (D)

Maisonneuve fracture is an injury pattern caused by an eversion/external rotation force that starts at the ankle and transmits up the leg. It characteristically includes a spiral fracture of the proximal fibula, disruption of the distal tibiofibular syndesmosis, and injury to the medial side of the ankle (often a deltoid ligament tear or a medial malleolar fracture). The distal tibial plafond, or pilon fracture, involves the articular surface of the distal tibia itself and results from a different mechanism, not part of the Maisonneuve pattern. So the statement that is not part of this injury pattern is a distal tibial plafond fracture.
